From 2008 Volvo introduced a new type of flywheel for these cars.
They did this to increase the lifespan of the clutch.
The old type of flywheel is no longer available.
If the old flywheel is replaced with the new type, then the clutch must also be replaced. Otherwise, the clutch does not fit on the flywheel.
In that case: use RD31367470. (see related products)
